EE Journal: CMOSIS announces a 20MP global shutter sensor for industrial applications. The new CMV20000 sensor features 5,120 x 3,840 resolution with 6.4 um sized pixels resulting in an active sensor area of 32.8 x 24.6 mm (35 mm film optical format). Its peak QE is more than 45%, responsivity is 8.29 V/lux.s, and DR is 66 dB. The 8T pixel is said to reduce dark noise and FPN of the sensor.

At full 20MP resolution and with a 12-bit ADC resolution the CMV20000 delivers 30 fps. This is achieved by using 16 LVDS outputs running at 480 Mbit/s each. At full resolution and frame rate, the power dissipation is 1.1W. This power consumption can be dynamically controlled when lower frame rates are used.

Driving and programming the on-chip features such as HDR modes, offset and gain programming and power dissipation control is done over a 3-wire read-write SPI control.

The monochrome variant of the CMV20000 sensor is in production today. A color variant, with RGB Bayer CFA filter, will be introduced to the market in Q4 2012. It is housed in a ceramic 143-pin PGA package and can be operated in the -20 to +70 ºC temperature range.

The CMV20000 was originally developed as a customized, exclusive product aimed at complex traffic management applications. An agreement with the original customer allows CMOSIS to offer this imager to third parties for applications outside the traffic field.
